Printing process

The paper fed from Tray 1 or Tray 2 is carried by the paper feed roller, register roller L and transport
roller. When the paper is fed from the MPT, it is carried by the MPT paper feed roller and register
roller U. Then, an unfixed toner image is created on the paper transported onto the belt sequentially
through the electrophotographic process of KYMC. Thereafter, the image is fixed under heat and
pressure as the paper goes through the fuser unit. After the image has been fixed, the paper is
unloaded to the stacker either face-up or face-down stacker, according to the outputting method
selected by opening or closing the face-up stacker.
While the above refers to the one-sided print operation of the printer, its operation in two-sided print
will be explained below.
When two-sided print is conducted, the paper that has passed through the fuser unit following first
one-sided print is sucked into the Duplex unit by the separator DUP. After entering the paper
reversal transport path, the paper is carried from there to the inside of the Duplex unit by the
inverting operation of the reversal roller. Then, after passed through the Duplex unit by the
transport roller that is located on the transport path inside the Duplex unit, the paper is fed along
the paper feed route of the Duplex unit to eventually merge the same route that comes from the
tray. From here on, the same operation as that of one-sided print of paper fed from the tray takes
place.
